ANR was caused by "SharedPreferences"?

[LazyBonesLZ]

After integrated Max SDK v11.3.3, ANR rate seems too high, I checked some stack traces info and log , and found some details log contained keywords "com.applovin.sdk.impl.isFirstRun", could you help to find if ANR is related with it? stack trace like this:

FYI, details info was collected by ANRWatchDog and ACRA SDK, the follow screenshot is part of the details info:

@LazyBonesLZ - Thanks for reporting this. We can investigate, but in the meantime you can initialize our SDK (basically, any calls to AppLovinSdk.getInstance(...) in a bg thread to work around this.

Hi, thanks for your reply. You mean I should initialize SDK in a thread but not on main thread?

following is my code:

BaseApplication.runOnUiThread(()->{
                        AppLovinSdk.getInstance( mainActivity ).setMediationProvider( "max" );
                        AppLovinSdk.initializeSdk( mainActivity, new AppLovinSdk.SdkInitializationListener() {
                            @Override
                            public void onSdkInitialized(final AppLovinSdkConfiguration configuration)
                            {
                                // AppLovin SDK is initialized, start loading ads

                            }
                        } );

                    });

That's the opposite of what I'm suggesting, you can run code in a background thread using AsyncTasks, ExecutorService, WorkManager, etc. You're running code in the UI/Main thread here.
